To all whom it may concern:

Be it known that I, CLARENCE E. VVIsn, citizen of the United States, residing at \Vashington, District of Columbia, have invented certain new and useful Improvements in Portable Hand-Tools for Stretching, Tightening, and Twisting the Free Ends of WVire Lengths, of which the following is a specification. v

This invention relates to a portable hand tool for stretching and twisting the free ends of wire lengths to assure the' tight twisting of said ends of the wire for sc curely oining the said ends together, and

is especially designed. for the purpose of stretching or tightening the wire which-is frequently employed in securing together the sections of a knock-down or collapsible crate used for shipping purposes by clamping the terminal ends of the wire and twist ing the free ends until the said ends are tightly and securely joined.

The prime object of this invention isto 7 provide a novel, simple, strong, economical, durable and thoroughly reliable and eilicient tool for the purpose of stretching or tightening and twisting the free ends of wire lengths, so that the said lengths will be properly tightened around a receptacle and the ends will be caused to be safely, firmly and securely oined together by the twisting operation thereof.

Anotherobject of the invention is to so construct my novel device that when each free end of a wire length which has been passed 01' secured around a receptacle to bind the same shall have been firmly secured between the jaws of the tool the handle portions of said tool are pressed together,

. which action causes the jaws to be separated, thereby stretching or tightening the wire at its joinin point, and at the same time the handles are secured in the closed posi-' at the point of their juncture sufliciently to secure the stretching or tightening tension of the wire, whenthe handle securing means is detached and said handle allowed to separate, thus relievlng the tension on the wire at and near the point of juncture, the. tool then being given a sufiicient number of turns to properly and securely join the ter provide simple and efficient means for effecting the clamping, stretching or tightening, holding and releasing of the wire ends for the purposes such as set forth.

The foregoing and such other objects as may appear fromthe ensuing description are attained by the combination, arrangement, location, and novel features of the construction of the parts hereinafter more fully described, illustrated in the accompanying drawings and particularly pointed out in the claims appended hereto, it being understood that slight changes in the form, proportions, and minor details of the'eonstruc tion may be resorted to without departing E i from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings which form a part of the specification it will be seen that:

Figure 1 1s a plan view of the novel vice embodying my invention, showing the ends of the wire passed between the. clamping. jaws, and showing a portion of a top and sidcsection of a knock-down or collapsible crate or other receptacle to which a binding wire has been secured, and

Fig. 2 shows an edge view of the device shown'in Fig. '1.

Similar characters of reference are employed to designate corresponding parts throughout theseveral views in the draw ings. v j

In carrying out my. invention it will be seen that it comprises two main levers or members 1 and 2 which are'pivoted together by a suitable pin 3, the integral acting ends or fixed aws 4, 4 each being provided near its outer end with an extended portion 6 for the receptionofone end of a wire length, and each of said fixed jaws-having an integral projecting rib 6 for the purpose hereinafter. referred to.

Secured to "the outer face of each of the members 1' an 2, at the acting end portion thereof, is a longitudinally slidable member constituting a movable jaw 7, provided with elongated slots 8 therethrough, said slots being adapted to receive the headed ins '9 for the purpose of securing the mem ers 7 ,to the members 1 and 2 and also serving crimped and twisting operation of the 'of the members 1 and 2 for locking the movablejaw in its clamped re- 9 ends are clamped between I by a double headed pin 1 as a guiding sliding movement of the members 7' in their forwardly and rearwardly movement. The outer end of each member 7 is provided with a recess forming a semicircular groove or seat'9, .so-that when the ends of the wire to be stretched .or tightened and twisted are passed between 9, and clamped between the-movable and rigid clampin jaws, the wire will be rmly secured between said jaws until the stretching, tightening and wire ends shall have been suitably completed.

The outer edge of each of the slidable members is provided with ratchet teeth 10, which teeth are engaged by the toothed end of aspring pressed pawl 11, carried by each the-purpose of lation with the rigid jaw when the -wire the said movable and rigid jaws, and for releasing the movable jaw when from between the jaws. To each of the membersgl and 2 is secured, at its inner headed portion one end of a coiled spring 13, the other end of said spring being secured to the outer end portion of the slidable or movable member 7 for he purpose of withdrawing the movable member from its clamped position when ,the' pawl 11 is disengaged from the ratchet teeth 10, as will be readily understood, and at the outer headed portion of the pin 12 is secured a chain adapted to lock the members 1 and 2 in their closed position until the ends of the wire which have been clamped between the jaws of the tool have been given the desired stretching, tightening and twisting action at the point of juncture, sufliciently only to secure the tension on the wire when the locking means is released, the members 1 and 2 allowed to separate and the twisting action thencontinued to properly finish the twisting of the ends of the wire securely together. i

, Each memberl and 2 is provided with a lever. 14, pivoted thereto by a suitable securing-pin 15, each of said levers having an outer handle portion 16 and an inner cam-shaped portion 17, which cam-shaped portion is adapted to engagp with the outer end of the movable Inem er 7 whenv the lever is pressed inward, thereby forcing saidmovable member to slide forward to clamp the wire between the rigid and mov able jaws, and when the said levers 14 the cam-shaped inare moved outwardl 'ner end portion will be disengaged from the outer end of the movable' ,member, and, the spring-pressed the tension exerted y the coil spring 13 will immediately retract the movable 'member means during the longitudinal the rib 6' and groove or seat 'bersl and 2 together,
